3.Programming to the EPROM

In EPROM mode, the MB89P928 functions equivalent to the MBM27C1001A. This allows the PROM to be

programmed with a general-purpose EPROM programmer (the electronic signature mode cannot be used) by

using the dedicated socket adapter.

• Programming procedure

(1) Set the EPROM programmer to the MBM27C1001A.

(2) Load program data into the EPROM programmer at 0FE4H to FFFFH.

(3) Program with the EPROM programmer.

4. Recommended Screening Conditions

High-temperature aging is recommended as the pre-assembly screening procedure for a product with a blanked

OTPROM microcomputer program.

Program, verify

Aging

+150 °C, 48 Hrs.

Data verification

Assembly

5. Programming Yield

All bits cannot be programmed at Fujitsu shipping test to a blanked OTPROM microcomputer, due to its nature.

For this reason, a programming yield of 100% cannot be assured at all times.

6. EPROM Programmer Socket Adapter

Package

FPT-80P-M06

Compatible socket adapter

ROM-80QF-32DP-8LA

Inquiry: Sun Hayato Co., Ltd.: TEL 81-3-3802-5760

Note: Depending on the EPROM programmer, inserting a capacitor of about 0.1 µF between VPP and VSS or VCC

and VSS can stabilize programming operations.
